Propanefueled

Propanefueled describes devices and systems that run on propane, a hydrocarbon gas burned for energy. Propane is categorized as a liquefied petroleum gas (LPG) and is stored as a pressurized liquid that vaporizes for combustion.

Common uses include autogas vehicles, residential and commercial heating and cooking appliances, water heaters, portable stoves, camping equipment, and forklifts. Propane-fueled appliances are often preferred for their clean combustion, quick heating, and wide availability of cylinders and tanks. In transportation, propane engines can be converted from gasoline or built for dedicated LPG operation; fueling is typically done at specialized LPG stations or with home refueling options in some regions.

Advantages include reduced particulate and sulfur emissions compared with coal or heavy fuels, rapid start-up and quiet operation, and lower fuel cost in regions with established LPG infrastructure. Limitations involve lower energy density by volume than gasoline, leading to shorter range between fills; performance can be affected by ambient temperature; and the availability of refueling networks varies by geography. Safety considerations include the odorization and leak-detection, proper storage in approved tanks, and compliance with codes and standards. Propane is heavier than air and can accumulate in low-lying spaces, posing explosion and asphyxiation risks if not properly vented. Regulators, safety valves, and regular inspections are required by standards such as NFPA 58 in the United States and equivalent codes elsewhere.
